Warning:
To prevent personal injury, always observe Good Laboratory Practice when
handling solvents, changing tubing, or operating the detector. Know the physical and
chemical properties of the solvents used (see the Safety Data Sheets for the solvents
in use).
Warning:
To avoid electric shock, observe these precautions:
• Do not remove the mass spectrometer’s protective panels. The components they
cover are not user-serviceable.
• When the instrument is in Operate mode, avoid touching the areas marked with the
high voltage warning symbol. To touch external areas marked with the symbol, first
put the instrument in Power Save mode.
Warning:
To avoid burn injuries, take great care while working with the probe and
source; these components can be hot.
Warning:
To avoid injury, ensure that these criteria are met when performing
maintenance operations inside the source enclosure:
• The instrument is in Power Save mode.
• LC flow is diverted to waste or set to Off.
• Desolvation gas flow is stopped.
